IMPROVEMENT 'IN HYDRANTS.

To all whom it may concern Be it known that I, JAMES FARNAN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and improved Combined Hydrant and Street-Washer; and I do hereby declare that the following is a full, clear, and complete description of the same, reference being had 'to the accompanying drawing making a part of this specification, in which- Figure l is a side view ofthe apparatus.v

Figure 2 is an end view.

Figure 3 is a vertical transverse section.

Figures 4 and 5 are detachedsections.

Like letters of reference refer to like parts inthe several views.

The nature of this invention relates to that class of water-dischargers vknown as hydrants; and

The object of the same is to produce an eicient, simple, and safe means of drawing water from the water-mains for sprinkling the streets, lawns, and other needful purposes.

A full and complete description of the same is as In the drawing, fig. 1-

A represents a section of pipe, the length of which being more 01 less, as may be required, to connect the upper part of the apparatus above the ground to that part in the ground, and by which it is attached tothe water-mains.

To the upper end of the connection-pipe A referred to is attached achamber, B, from the side of which projects a pipe, O, from which the water is discharged,

'lo the lower end ofthe pipe A is attached a chamber, D, fig. 3.

Vertically in the center of said chamber is secured (by the lugs E) a cylinder, F, an end-view of which is shown in iig. 5, in which it will be seen that there is an annular space, I, between the cylinder and the inside of the chamber D, so that a direct com munie-ation exists between the parts of the chamber above and below the cylinder therein.

In said cylinder is tted a valve, G, attached to the lower end of a stem, H, a detachedv view of said valve 4and stem being shown in ng. 4.

The lower part of the valve referred to is made of leather or of other suitable material, which, when the valve is screwed down by means of the'thread J, at the' upper` end of the stem, is forced upon the seat K, g. 3, screwed into the end of the chamber.

Said seat also answers as a coupling, whereby'the apparatus is connected to the water-main, the valveseat and coupling being a screw-nut, L, as shown.

The valve-stem referred to is constructed in two l pins a.

by means of a link, M, secured toA each section by As aforesaid, the upper end of the valve-stem is provided with a s iew, J, Vof a coarse pitch so that it will move the steniiiand valve quickly.

Said screw is tted in a nut, Nl, iig. the upper end of the chamber B.

The part of the stem immediately above the'screw is plain, as shown at O, gs. 3 and 4, and which passes through a stuffing-box, P, fig. 3, forming apart of the nut N, and into which is fitted a jaw-nut, Q, whereby the packing in said box is compressed around the said stem.

By this means the upper end of the stem in its passage from the chamber to the outside is made watertight. Also contributing to this end is a collar-,'R, iig. 4, immediately below the thread J, which, when 3, screwed into the valve is screwed up from its seat, as shown in lig.

3, presses against the under side of the nut N, thereby preventing any escape of water from the chamber B around the stern or valve-rod to the outside.

Having described the construction of the apparatus I will now yproceed to explain the operation of the same, which is as follows:

As above said, this device is connected to the watermain, buried in the ground, by means of the nut L.

On applying alrey to the external end S of the valve-stem the valve, by means of the screw J, will be raisedV from its seat, as shown in fig. 3.

The water will now ow into the chamber D, thence through the pipe A into the chamber B', from thence through the pipe O to the. outside or into a hose attached thereto by means of the screwA. The course of the water is indicated by the arrows in ifig. 3.

It will be obvious that the water dows into the chamber D through the annularl space I surrounding the cylinder F, and that it can be shut off therefrom by screwing down the valve, which will close the opening B of the valve-seat, and again belet on by screwing it up, as shown in lig. 3.

\ As before stated, the pipe A may be of any length necessary to reach from the water-main to the surface of the ground. Hence, to adjust the valve-stem to the length of the pipe, it is made in two sections, and which are connected to each other by a link, M, referred to.

On closing the valve, thereby shutting oli the water,

more or less will remain above the valve, which is al- Y lowed to escape from the pipe through a small hole, l), fig. 1, bored in the side of the chamber D through one of the lugs E into the cylinder, as indicated by the dotted lines bin g. 5. The position of `said hole in vits relation to the valve is such that, when the valve is shut down, it will be above the valve, so what water -may have remained in the pipe and chamber will iow out therefrom; and Whereas, when the valve is open, as shown in iig. 3, the hole is covered by the valve, thereby preventing waterl from owing out therefrom or air to enter. By this relative position of the hole for the escape of the waste water no water is allowed to remain in the pipe to freeze and obstruct the working of the valve when shut down, and there is no waste of water through the hole when the valve is open, as
